Joe Magee was an animated character created by General Electric in 1942 to present the subject of arc welding, and always seems to do the "wrong thing". The original series consisted of six, ten minute films; but in this re-release they are condensed and extended into two, 20 minute films. Welding is a crucial process in the metalworking industry, primarily focusing here on shielded metal arc welding (stick welding). It involves striking an electric arc between a covered metal electrode and the workpiece to melt and join metals. Proper safety gear, such as helmets, gloves, and goggles, is essential to protect against the intense heat and light. Successful welding depends on controlling key factors like arc length, electrode angle, current settings, and travel speed. The electrode coating generates a protective gas shield and slag to prevent contamination of the molten metal. Common welding defects include undercut, overlap, and porosity, which can be minimized by maintaining a steady arc and proper technique. Machines provide adjustable current with AC or DC power, and welding positions require specific angles and settings to manage issues like arc blow. For longer welds or multiple layers, slag must be removed between passes, and craters at the ends of welds must be properly filled to avoid cracking. Overall, achieving a good weld requires careful control of the molten pool, consistent motion, and attention to detail throughout the process. 0:00 Importance of welding in the metalworking industry; focus on shielded metal arc welding (stick welding). 1:18 – Protective gear like gloves, helmets, and flash goggles. 1:46 – Overview of welding transformers providing AC or DC current with precise control. 2:03 – Introduction to different types of electrodes and their coatings. 2:25 – Four cardinal points of welding: arc length, electrode angle, current setting, and travel speed. 2:37 – Demonstration of arc striking methods: scratching and tapping. 3:37 – Description of arc heat, metal melting, and formation of the weld bead. 4:22 – Role of electrode covering in shielding the arc and forming slag. 5:13 – Definitions of common weld defects: undercut, overlap, and porosity. 5:50 – Recognizing proper arc by the steady frying sound. 6:08 – Post-weld inspection: uniform ripples, flat face, good penetration. 6:40 – Problems from incorrect arc length: too long causes spatter; too short causes inclusions. 7:40 – Importance of maintaining correct arc length by feeding electrode consistently. 8:01 – Electrode angle affects bead quality; extreme angles cause distortion. 8:15 – Welding power sources explained with current control methods. 9:02 – Arc voltage is governed by arc length, not machine voltage setting. 9:40 – Flat position welding defined by angle limits; electrode size and current settings discussed. 10:20 – Uniform weld shape and slag removal after completion. 11:26 – Restarting welds: remove slag and strike arc slightly ahead of crater. 12:00 – Importance of filling the crater at weld end to avoid cracks. 12:29 – Direct current welds require electrode angle changes to counteract arc blow. 13:25 – Arc blow explained and mitigated by adjusting electrode angle. 14:13 – Groove weld technique in flat position involves weaving for good edge fusion. 15:04 – Multi-layer groove welds require slag removal and uniform layering. 15:18 – Horizontal fillet welds defined with positional limits and current settings. 16:19 – Good horizontal welds require proper electrode manipulation and pool control. 17:01 – Electrode angle adjustments again used to combat arc blow during long welds. 18:04 – Cleaning slag and reestablishing molten pool for multiple electrodes. 19:01 – Proper fusion between weld passes is critical in multi-layer welds. 20:00 – Crater filling and breaking the arc correctly complete each weld pass. 20:34 – Final weld appearance should show good fusion, minimal undercut, and consistent face. Motion picture films don't last forever; many have already been lost or destroyed. For almost two decades, we've worked to collect, scan and preserve the world as it was captured on 35mm, 16mm and 8mm movies -- including home movies, industrial films, and other non-fiction. If you have endangered films you'd like to have scanned, or wish to donate celluloid to Periscope Film so that we can share them with the world, we'd love to hear from you.
